Aim: identification of astrocytic glia cells impregnated to determine the hypoxic changes in nerve tissue. Material and methods. Condition of hypoxia was simulated in laboratory rats with "jar hypoxia". For the impregnation of histo-logical sections were used as a basis for the method of Rio-Gortega. Results. Silver impregnation method revealed several morphological forms of astrocytic cells in hypoxic changes in the nervous tissue of the brain. Conclusion. There were marked morphological brain astrocyte cell forms reflecting their functional state. Traced compensatory changes astrocytic cell depletion of these processes and the appearance of pathological morphological characters, up to the fragmentation and destruction of cells.

The Purpose: to determine the acute toxicity of new metal complexes of iron derived vinylimidazole and to reveal their antihypoxic activity in comparison with Acyzol and other known antihypoxic etomersol and hypoxen. Material and methods. Antihypoxic activity was studied in experiments on nonlinear white mice-males 4 models of acute hypoxia (hypobaric, hypoxia with hypercapnia, hemic, histotoxic). Rates of acute toxicity (LD16, LD LD ) were calculated graphically by the method of Miller and Tainter. Changes in oxidative metabolism in mice under the influence of the most active compounds were assessed by the values of oxygen consumption and rectal temperature. Results. The studied metal complexes of iron are small and moderately toxic. The connection under the code of Tetravim on the severity of antihypoxic effect (the increase in life expectancy male mice compared to control groups on 20-127%) in the range of doses studied (5-250 mg/kg, i/p) is superior to other derivatives of vinylimidazole known and antihypoxic: etomersol (25-100mg/kg, i/p) and hypoxen (50-150 mg/kg, i/p). Conclusion. The obtained data on the pharmacological activity of Tetravim require further clarification of the mechanism of antihypoxic effect and clinical trials with the aim of putting it on the drugs market as a promising antihypoxic agent.

The objective: In order to improve exercise capacity in the middle-altitude conditions a technique of urgent adaptation with use of the compact device has been developed. Material and Methods. The study included two groups of people involved in mountain tourism, on the move and stay in the midlands, which used (experimental group) and didn't use (control group) the developed technique. Considering the specificity of observations directly on the mountain route, the compact equipment and functional studies (pulse oximetry, spirometry, peak flow, the dynamic measurement of pulse and blood pressure with the calculation of double product index) were used to monitor the experiment. Results. During the experiment changes of the data characterizing positive development of the functioning of human cardiore-spiratory system during the physical activities in the conditions of middle mountains were recorded (peak expiratory flow rate (from 512,86 to 592,86 I / min, t = 2,25, or by 115,6% in the experimental group) and double product index (from 95,66 to 127,09 units., t = 2,41, or by 132,9% in the experimental group). Conclusion. Thus, the offered device and its technique compose an effective scheme of preliminary preparation of cardiorespiratory system to stay in the middle-altitude condition and can be recommended for use in need short-term adaptation.

We studied neural induction and generation of neuroectoderm in the colonies of human parthenogenetic SC cultured in the presence of 5 and 19±2% oxygen. We found that neuroectoderm was more actively generated at high oxygen content. At the same time, the transcription of stem cell pluripotency genes was not completely suppressed during neural induction at low oxygen content, while the expression of endoderm and mesodermal marker genes attested to the absence of specifi c differentiation. These fi ndings demonstrate more effi cient neuroectoderm generation induced in the colonies of pluripotent stem cells under conditions of normoxia.
